Title: Improvements in and relating to the high pressure polymerisation of ethylene
IPC: C08F10/00
Filed: 1963-07-11
Abstract: 1,012,247. Automatic control of polymerization. HALCON INTERNATIONAL, Inc. July 11, 1963 [July 18, 1962], No. 27525/63. Heading G3R. In a process of polymerizing ethylene under high pressure in an elongated reactor the linear velocity within which is increased periodically, the integral of reaction temperature taken over the period of each pulse is compared with the integral for the preceding pulse, the next interval between pulses and/or the linear velocity during the next pulse being varied as necessary to produce a constant integral and hence amount of polymer deposition. As shown, ethylene gas and a catalyst such as oxygen are fed at 11 to a reactor 10 having a preheating zone, a reaction zone, and a cooling zone the temperatures of which are controlled by surrounding water jackets. The polymer and gas are exhausted to known processing apparatus at 16. Pulsing is controlled by an integrator-type timer 26 which is effective through a selector switch 28 and an actuator 38 to adjust an exhaust valve 14 to increase the rate of flow until a comparator 40 indicates that reactor pressure as measured by a strain gauge measuring device 24 has fallen to a predetermined value. Between pulses the pressure within the reactor is maintained constant by pressure measuring device 24 controlling valve 14 through a further actuator 36 which is rendered effective by selector switch 28. The output of a thermocouple 18 measuring the temperature within the reactor is applied to a computer 22 which integrates over the period of a pulse and stores the result for comparison with the next integration. Any difference controls timer 26 to alter the period before the next pulse and/or the setting of valve 14 during the next pulse. Several computers may be associated with differently located temperature responsive devices, e.g. 18, 18a, and the integral having the greatest deviation is automatically selected to control the reactor. Failure to correct is indicated by an alarm 43. Specifications 816,110 and 1,000,308 are referred to.

Title: Improvements in and relating to carburettors
IPC: F02M23/09
Filed: 1931-10-05
Abstract: 387,039. Spray carburetters. SCHAFFNER, F. W., 409, Himrod Street, Brooklyn, New York, U.S.A. Oct. 5, 1931, No. 27647. [Class 7 (iii).] Liquid fuel is supplied from a float chamber 8 to a T-shaped nozzle 12 over which is disposed a pair of sliding plates 5 for controlling in succession a number of orifices 13, one orifice remaining open for slow running conditions when the plates are closed. The plates 5, which also control the air supply past the nozzle, are provided with notches 59 which prevent the closure of the last orifice. The plates are actuated by a throttle valve 21, Fig. 16, constructed in two parts so that in the closed position a narrow passage between them permits the flow of mixture during slow running of the engine. The parts are mounted on shafts 20 geared together at one end by wheels which actuate the plates 5 through levers 26, 27 ; at the remote end of one of the shafts is an operating lever 24, and a lug 36 which engages a forked member 35 carried by an annular member 33 which controls an extra air supply to the mixing chamber. A foraminous airfiltering screen 37 is placed over the openings 34, 32. If desired, the lug 36 may be replaced by a hand control device fitted to the air admission member. Auxiliary air is admitted past a suction-actuated valve 7, a slight depression being sufficient to open a plate 54 against a spring 55 and a larger depression opening a plate 49 against a spring 50. The relative movement of the plates 49, 54 is limited by a stud 58 carried by the plate 54. By adjusting the elements 41 the size of the chamber adjacent the nozzle is altered in capacity. The mixing chamber may be jacketed for heating purposes.

Abstract: 502,946. Elastic - fluid turbines. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Sept. 22, 1938, No. 27680. Convention date, Oct. 26, 1937. [Class 110 (iii)] In a blade drum for radial-flow elasticfluid turbines the centrifugal force is taken by rings 8, Figs. 2 and 5, engaging notches in the blades 6. The walls 18 of the notches form distance pieces between adjacent blades. The rings 8 for the outermost blade ring may be formed with integral stiffening ribs 9, Fig. 6, and the other rings 8 may have similar ribs, limited in height by the radial clearance between the blade rings. The blades 6 may be secured to the rings 8 by lips 10, Fig. 10, which may be previously formed on the blades and sprung over the ring 8, or may be formed by a pressing operation after positioning the blades on the ring. The sides of the notches may slope inwards towards the bottom, the ring 8 being correspondingly shaped. The distancing walls 18 may be dispensed with, the notches then being cut in blades of uniform section. In a modification, the ring 8 is formed on its sides with grooves 16, Fig. 15, conforming to the cross-section of the blades which are slightly thickened around the notches, and on its inner face with grooves 14 which accommodate the portions of blade defining the bottoms of the notches.

Abstract: 286,997. Heyne, W. 0., Clark, A. G., and British Electric Pari-Mutual, Ltd. Sept. 28, 1927. Totalizators.-In means for transmitting intermittent angular movements particularly applicable for the transmission of the movements of the primary setting or registering device of a totalizator a quick screw thread or equivalent device is adapted to impart endwise movement to one member of a positive clutch for the purpose of putting the transmission mechanism into and out of driving engagement with a constantly rotating driving member. The apparatus as shown in Figs. 1 and 2, designed for embodiment in the registering mechanism described in Specification 287,767 comprises a constantly rotating pulley d exerting a constant torque, through a friction clutch e, upon a spindle f carrying a series of electrically controlled escapement devices and a sprocket wheel b adapted to receive movement, through a positive clutch c, from the pulley d and to transmit the movement to the counter drums by a chain drive a. To produce equal angular movement of the counter-actuating shaft g by the intermittent movements of the spindle f the spindle has attached thereto a sLeeve h with a quick screw thread i working in a corresponding thread in the hub of the sprocket wheel b so that under control of the escapement devices the clutch is engaged and disengaged by the axial movement of the sprocket wheel to transmit the angular movements to the shaft g. To accelerate this movement at the end of the actuation the sprocket wheel k is provided with a notched disc l co-operating with a spring-controlled roller m; this accelerating device may be applied to the sprocket wheel b. The disc l carries pins b cooperating with radial slots q in a wheel r to transmit the movement to the first drum of the counting train.

Abstract: A low-temperature tough steel is produced by adjusting the nitrogen content in a molten steel of carbon content not more than 0.15%, as refined in an open-hearth or electric furnace or in a converter, to be 0.008-0.04% by adding nitrogen gas or a nitrogen-containing alloy such as Mn-N, preferably simultaneously adjusting the ratio of C:O by weight to 3/4 in the molten steel by adding a deoxidizing agent such as Mn, Al, Si, C or alloy thereof e.g. Si-C-Fe, and then vacuum degassing the steel.  An example of a steel alloy which may be produced, rolled into sheet and normalized for one hour, has the composition: C no more than 0.15%, Al 0.01-0.1%, Mn 0.5-2%, Si 0.01-1%, N 0.005-0.02%, and if desired one or more of Nb, Ta, V totally 0.01-0.02%, Fe and impurities as balance.
